Heat pumps, rebates and the 50°C rule

Many Sydney households replacing an electric tank now look at heat pumps, which NSW's Energy Savings Scheme has discounted for eligible homes — check current offers before you buy. Whatever you choose, a new installation must deliver water to bathrooms at no more than 50°C, usually through a tempering valve, so ask the plumber how that will be fitted.

Common questions

Should I replace my Sydney electric hot water tank with a heat pump?
It can cut running costs, but it depends on where the unit can go, noise near bedrooms and your electricity tariff. Ask the plumber to compare options for your home and check what discounts apply.
Who fixes a leaking hot water system?
A plumber who works on hot water systems can inspect the leak. A gas or electrical fault may also need a tradesperson licensed for that work.
Should I repair or replace the unit?
That depends on the failed part and the condition of the unit. A clear photo of the label helps a tradesperson identify the model before advising you.
